APPARATUS FOR BURNING PETROLEUM.

SPECIFICATION forming part of Letters Patent N0. 412,875, dated October 15, 1889.

Application filed January '7, 1889. Serial No. 295,682- (No model.)

To all whom it may concern:

Be it known that we, GEORGE COLLINGS and EDWARD H. WEATHERHEAD, citizens of the United States, and residents of Cleveland, county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in Apparatus for Burning Petroleum,

of which the following is a specification, the- Referring to the drawing, the figure is an elevation view of our improved apparatus, parts being broken away andin section.

A is a boiler extending into the fire-box, beneath which is the burner a, provided at its outer extremity with air-valve a, which controls the supply of air issuing from pipe a into said burner. A pneumaticpump or air-compressor B is suitably located adjacent to air-storage tank C, and connectedtherewith by pipe 0, provided with valve 0. Said pump has connected with it, respectively, inlet and outlet pipes 7) I), the former of which is provided with valve 11 and water-pressure regulator Z). Leading from storage-tank C to the burner is the air-supply pipe a that is provided intermediate of said tank and burner with pressure-regulator a by means of which the pressure of air passing from tank to burner may be regulated.

Oil-reservoir D is located in the subterranean cistern E, in a horizontal plane below the level of the plane occupied by burner a. Said reservoir is provided with vent-pipe 61, having valve 61, and with stand-pipe 01 closed by plug (Z Said reservoir is further provided with oil-gage e, that is in turn furnished with the usual valve 6 at its upper and lower extremity. Cover t closes the top of cistern E. Connecting the air-storage tank and the reservoir is pipe F, provided with valves f, and also having located thereon the air-pressure regulator f and gage f by means of which the pressures between the storage-tank and the reservoir may be respectively regulated and gaged. Pipe G connects the reservoir with the burner, and is provided with the customary valve 9, and also with checkvalve g, that lifts in the direction of the flow of the oil from the oil-reservoir to the burner, and seats as soon as back-pressure occurs.

The operation of the apparatus is as follows: The pneumatic pump B is, by means of pipe I), connected up to suitable actuatingpower, the power applied being regulated by regulator b Compressed air is forced by said pump into the air-storage tank C, thence is drawn through pipe a in one direction to burner a, there to be utilized to supply the required oxygen to perfect the combustion of oil also issuing from said burner. of the regulator d the supply of air passing through pipe C62 may be readily controlled to insure the exact amount required for perfect combustion. In the other direction the air issues from the storage tank and passes through pipe F to the oil-reservoir, the pressure in said pipe being indicated by gage f and regulated by regulator f This pressure of air on the oil within the reservoir forces the oil outward into pipe G, whence it flows to the burner.

It is apparent that by means of this apparatus the danger from fire is greatly lessened, as the oil ceases to flow to the burner theinstant the air-pressure is removed from the reservoir. Any backward flow of oil from the burner is prevented by checkvalve g, and thus all danger of the oil catching fire and working backward to the reservoir is prevented,

By means of the regulators f and a we may easily regulate to different pressures the air issuing, respectively, into pipes F (L as may be needed to secure the perfect and economical consumption of the oil. In the common gravity-feed there is no evenness and regularity of the flow of oil. It will be noticed, further, that the pneumatic pump is located in suitable juxtaposition to the burner, and that the air-storage tank of said pneumatic apparatus has independent connections, respectively, with said reservoir and burner, through pipes F and (L2, respectively.

By means Pipe H connects pipe (1 with the oil-pipe G. On said pipe H is located atwo-way cook 71 provided with lever h and vent h, said lever being connected with valve a by means of chain a, so that when said valve is closed the said lever is also and by the same movement turned so as to open vent h and close communication between pipes a and H. At its opposite extremity pipe H connects with pipe G and terminates in a convex disk It, provided with a flexible diaphragm g Held in engagement with this diaphragm is the head of the spring-pressed valve j. As the air-pressure is permitted to pass through pipe II, it causes the diaphragm to be depressed and the valve to be withdrawn from the customary seat, and thus the oil is free to flow upward along pipe G to the burner. When the valve a is turned and the air issuing from pipe (1 passes out of vent h, the pressure is at once relieved within the pipe, and the spring-pressed valve 3' immediately and automatically seats itself, thus cutting oif all possibility of a'further supply of oil being fed to the burner. It thus occurs that whenever the burner is shut off the feed toward the burner is also automatically and synchronously interrupted and all danger of fire avoided.

The foregoing description and accompanying drawing set forth in detail mechanism in embodiment of our invention. Change may be made therein, provided the principles of construction respectively recited in the following claims are employed.

We therefore particularly point out and distinctly claim as our invcntio11- 1. In apparatus for burning petroleum, the

combination, with an oil-burner, an oil-reservoir, and pipe-connection between the two, an air-compressor, and a pipe between the latter and said oil-reservoir, together with a pipe between the air-compressor and the oilburner, of a spring-pressed valve which controls communication between said oil-reservoir and said oil-pipe, and air-pipe between the air-compressor and said spring-pressed valve, said latter pipe provided with an escape-valve, together with a mechanical conneotion between said latter Valve and the valve of the oil-burner, substantially as set forth.

2. In apparatus for burning petroleum, the combination, with an oil-burner, an oil-reservoir, and pipe-connection between the two, an air-compressor, and a pipe between the latter and said oil-reservoir, together with a pipe between the air-compressor and the oil burner, of a spring-pressed valve j, which controls communication between said oil-reservoir and said oil-pipe, and a continuous airpipe H between the air-compressor and said spring-pressed valve, said latter pipe provided with a two-way escape-valve W, said valve provided with lever it, together with chain-connection between said lever h and the valve of the oil-burner, substantially as set forth.

In testimony that we claim the foregoing to be our invention we have hereunto set our hands, this 5th day of January, A. D. 1889.
